Medications, including Kamagra 100 mg, are formulated to maintain their potency within a specific timeframe. Once past the expiry date, there is no guarantee that the medication will retain its potency or stability, which could affect its safety and efficacy. Expired medication may be more susceptible to contamination by bacteria, fungi, or other microorganisms, especially if it has been stored improperly. Using contaminated medication can lead to infections or other adverse reactions.
